To all whom, it may concern: v

Be itknown that I, AnoHrE G. Honnrsrnm, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in PressurevRegulators; and I do hereby declare 'the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the io same.

My invention relates to an improvement in pressureregulators, the object of the invention being` to provide a pressure-regulator with a valve for opening or closing the passage-way I5 leading to the pressureregulator to enable the latter to be readily taken apart and dismana tled for cleaning or repairs when necessary;

and with this object in view my invention consists, essentially, in the combination, with a 23 pressure-regulator, of a hand-valve located in a valve-casing which communicates with the casing of the regulator.

In the accompanying drawings, Figure l. is a view in side elevation of a combined press- 25 ure-regulator and shut-ofiI valve, and Fig. 2 is a longitudinal vertical section of the same.

A represents the casing, which is preferably made of a single casting and provided with two cylinders, B O. In cylinder B is placed 3o the balanced valve D, which latter consists of a piston, a, at its upper end and a conical valve, b, at its lower end, which engages a conical valve seat, c, formed on the casing. Between the piston and conical valve is formed an annular chamber, E, which is located adjacent to the inlet-port F of the pressure-regulator cylinder, so that as steam, gas, or water flows through the inlet-port Fit will enter this annular chamber, surrounding the valve, and

4o eXert an equal pressure upwardly and downwardly on the valve, and consequently balance it as against pressure from the supply pipe or main. On the stem of the balance-valve or connected therewith are weights G, which opcrate to force the valve downwardly and allow the steam or water supply to llow past the valve and out of the exit-port f. IVhenever the pressure in the service-pipe connected with the exit-port f exceeds a predetermined 5o amount, such excess of pressure will exert itself upwardly against the closed head of the balanced valve and raise the latter, and thus cut off the supply of gas or steam to the service-pipe and cause it to remain shut olif until the pressure in the service-pipe has decreased 5 5 to the proper and predetermined amount, when the valve will again drop and admit a further supply. As I have in an even application herewith made claims to this construction of pressure-regulator, I make no claim vto it here- 6o in, but simply show and describe it as one form of pressure-regulator with which my shutoff valve is combined In cylinder O is located a piston-valve, H, the lower edge of which is ground with a eonical face, 7L, which is adapted to snugly seat itself on the conical seat z', formed on the outer casing. To the valve II is connected a screwstem, I, which extends upwardly through the screw-threaded cap K, and is provided on its 7o outer end with a handle or wheel, L. Vhenever it is desired to cleanse the balanced valve in order to insure its sensitive action in maintaining a uniform pressure in the service-pipe, the shut-off valve is screwed down firmly against its seat, thereby completely shutting olfall communication between the supply-main and the pressure-regulator. The cap lVI of the pressureregulator can be removed, the valve taken out and cleansed, the cylinder cleansed, So and the valve then replaced and the cap screwed on again. The shutoff valve is then opened and pressure admitted to the regulator again. The shutoff valve, being located in the same casing with the pressureregulator, adds but little to the expense of the device, while it adds very materially to its value, because it provides every pressure-regulator with means by which the supply thereto can be quickly shut off without interfering with the supply to any 9o other regulator and without causing any un necessary waste of time in inspecting, cleaning, or repairing the regulator.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a pair of inte grally-formed communicating cylinders, one cylinder being connected with a supply pipe or main and the other cylinder with a service- Ioo pipe, of a shut-off valve in one Cylinder and a pressure-regulator in the other, substantially as set forth.

2. The combination, with a pair of integral 5 Cylinders having a communicating passage, one cylinder being connect-ed with a supply pipe orinain and the other cylinder with a service-pipe, of a shut-off valve in one ey1inder and a pressure-regulator in the other, the Io latter having an annular' chamber therein adjacent to the communicating passage, snbstan tially as set forth. l 3. The combination, with a pair of integrally-formed cylinders having` a communicating passage, one Cylinder being connected With a snppiypipe and the other cylinder with a service-pipe, of a shut-oft' Valve in one cylinder, a pressure-regulator in the other, and screw-caps in each of these cylinders, whereby they may be opened and cleaned, substantially as set forth,

In testimony whereof I have signed this specification in the presen-ee of two subscribing` Witnesses.
